PATENT WILLIAM N. BRYAN, OF ADA, OHIO.

WINDMILL.

SPECIFICATION forming part of Letters Patent No. 259,476, dated June 13,1882.

- Application filed April 17,1882. (ModeL) 1 0 all whom it may concernBe it known that I, WILLIAM N. BRYAN, a citizen of the United States,residing at Ada, in the county of Hardin and State of Ohio, haveinvented certain new and useful Im provements in Windmills, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

My invention relates to an improvement in windmills; and it consists incertain improvements in the construction of the same which will behereinafter fully described, and pointed out in the claims.

The accompanying drawings fully illustrate my invention.

Figure l is a side elevation of my invention. Fig. 2 is an enlarged topplan view of the fanshifting mechanism. Fig. 3 is arear' elevation. Fig.4 is a side elevation from the opposite side shown in Fig. 1. Figs. 5and 6 are detailed views of one of the fans.

A represents the tower upon which the mechanism is supported, consistingof the tube a, secured to the base-frame b by means of the angle-ironsc, forming feet, as shown. At about midwayon the tube a is a collar,d,upon which rests the casting or spider c,having a hole cen' trallylocated for the insertion of the tube a, and radiating arms 6, adaptedto support the platform 6 the said platform being secured thereto bysuitable bolts, 0 Near their inner ends the arms 6 are perforated forthe reception of the eyebolts f, to which are secured the bracesf, whichextend downwardly and outwardly to the feet 0, to which they are securedby the bolts f which fasten the feet to the base-frame. Near the upperend of the tube a is a second collar, (4/, upon which rests the pivotedsupporting-bracket B. This bracket consists of the vertical bars I) bprovided at their upper ends with the bearings b for the shaft 0, thebars being connected by the hori zontal bar I) and the curved bar 11Bent at right angles to the bracket at the inner end, and formingintegral parts thereof, are the ears b bflwhich are perforated for thereception of the tube a, the lower one resting upon the collar a. Bymeans of these cars the bracket is pivoted upon the upper end of thetube.

Tothe outer end of the shaft (3 is rigidly secured the wheel Gr, nearwhich is loosely mounted a second wheel, G, of the same'size. From thewheel G radiate the arms g, to which the fans 9 are pivoted. These fansare made of any thin light material, preferably of sheet metal, so as tobe sufficiently strong to resist the action of the wind, and are curvedas shown in detail at Fig. 6, being connected to the arms 9 at the topby means of the ears 9 and at the bottom by means of the flat rods 9which are rigidly secured to the bottom of the fans at right anglesthereto, and are pivoted at their inner ends to the rod g, and arepivoted at their outer ends to the rods 9, which rods 9 are in turnpivoted to the periphery of the wheel G, as shown in Fig.2. By thuspivoting the fans they can be made to assume any desired angle to thewind by sliding the wheel G in and outupon the shaftO, as willbe readilyunderstood. This adjustment is accomplished automatically by means ofthe mechanism now to be described. The wheel G is provided with aninwardly-projecting hub, g provided with an annular groove, 9 In thisgroove is the strap (1 having the projecting ends ri to which arepivoted the upper bifurcated ends, (1, of the bent lever D, which ispivoted to the outer end of the bracket B at d. The lower inner end ofthe lever D is weighted, as at d, and is controlled from the ground bymeans of the rope E, secured thereto, which passes over the pulley F,secured to the bracket B, and thence to the ground, within easy reach.By this construction a governor is provided for the wind-wheel that willeffectually con-.

trol it, and when it is desired to stop it this can be effected bypulling the rope and causing the lever D to turn the fans edgewise tothe wind. Moreover, a rudder or vane is dispensed with, as, beingpivoted upon the tube, the wheel will always keep itself beforet-hewind, this being indicated by the arrows in Fig. 1 of the drawings.

H is the pump-rod, which passes up through the tube a, and is connectedat the top with a sleeve, h, which has a bearing end, h, in contact withthe inner edge of the bracket B, against which it slides, this beingnecessary to cause the sleeve to turn with the bracket as the windshifts. The sleeve It has its sides cut away at the upper portion,leaving only the two uprights b which uprights are bent in and pivotedto the upper end of the pumprod, as shown.

The motion of the wind-wheel is imparted to the pump-rod by means of thecrank-disk c, secured to the inner end of the shaft, and the connectingrod 0 pivoted to the disk at its upper end and to the end h of thesleeve h at its lower end. The crank-disk has a series of holes atdifferent distances from the center, into which the end of thepivoting-pin o is adapted to enter, by which means the length of thestroke of the pump-rod can be controlled so as to fit it for any make ofpump.

In order that the weight of the pump-rod may be no impediment to themotion of the wheel, I provide a spring, I, bent in the shape shown inFig. 4, the upper end of which bears under the projecting pin lbs, withwhich the pump-rod is provided near its upper end, the lower end of thespring being fastened to the top of the ear b of the bracket B. Thisspring isjustofsufficientlength to supportthe weight of the pump-rod,the downward stroke of the rod hearing against the tension of thespring, which assists in raising it up in its upward motion, thusequalizing the resistance 68 the wind-wheel at all points of the stroke.

Having thus described my invention, I claim 1. The tower A, consistingof the tube a, through which the pump-rod operates, the tube beingsupported by the angle brace-irons c and the braces f, the said braces fbeing secured to the spider 6, having radial arms 6, for supporting theplatform, and resting upon the collar d, rigidly secured to the tube,substantially as shown.

2. The wind-wheel consisting of the wheel G, rigidly secured to theshaft 0, and the second wheel, G, loosely mounted and adapted to slideon said shaft, and being provided with the pivoted radial arms g, havingthe fans g secured thereto, the arms 9, having the rods 9 rigidlysecured to them at the inner ends of the fans, the outer ends of therods g being pivoted to the rods 1 which are pivoted to the wheel G,whereby the rods g, carrying the fans, may be turned so as to presentthe fans at any desired angle to the wind by sliding the wheel G in orout upon the shaft 0, substantially as described. I

3. The wind-wheel consisting of the wheel G, rigidly secured to theshaft 0, journaled upon the pivoted bracket B, and the second wheel, G,loosely mounted and adapted to slide upon the shaft 0, the said wheel Gbeing provided with the hub 9 having the annular groove 9 in combinationwith the strap 01, the ends of which are pivoted in the bifurcated endsof the weighted bent lever D, pivoted to the bracket B, and controlledby the rope F, the wheel G being provided with the pivoted radial armsg, having the rods 9 rigidly secured to them at the inner ends of thefans, the outer ends of the rods g being pivoted to the rods g, whichare pivoted to the wheel G, whereby the fans may be turned at anydesired angle to the wind by raising or lowering the inner end of theweighted lever D, substantially as shown and described.

4. The pump-rod H, extending through the tubea, secured at its upper endto the sleeve h, which encircles the upper end of the tube a, the saidsleeve being provided with a bearing-lug, h, adapted to slide up anddown against the inner edge of the bracket B, motion beingimparted tothe sleeve h, and through it to the pump-rod, by means of theconnectingrod 0 and crank-disk c, secured to the inner end of the shaft0, all combined to operate substantially as specified.

In testimony whereof I hereby affix my signature in presence of twowitnesses.

WILLIAM NEPOLEON BRYAN.
